How to ensure that SSH is configured on the new node
Dear experts here:
I am going to add a new node to the oracle cluster. On this document:
http://docs.oracle.com/cd/E11882_01/rac.112/e16794/adddelclusterware.htm#CHDFIAIE
step 4, it asked me to "Ensure that SSH is configured on the node". Then I use root account to ssh to the new node(poseidon) from an existing node(elysium). However, it gives me the following error. When I switch to "mis" user, I can SSH in without any problem. Could anybody help me to verify if the SSH is configured well. thank you.
[root@elysium ~]# ssh poseidon

Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that the RSA host key has just been changed.
The fingerprint for the RSA key sent by the remote host is

Please contact your system administrator.
Add correct host key in /root/.ssh/known_hosts to get rid of this message.

One more question, if I want to disregard the password (so I don't need to input password every time) which should I do?
Also, how to set up log in welcome logo. thank you.
